[native-image] The string '{"typ":"JWT","alg":"HS256"}' doesn't have a valid JSON format.

There seems to be an issue with Graal native image JWT token verification (JSON decoding) using 0auth JWT library. The method works in standard JVM but fails in native image with the following error:

The string '{"typ":"JWT","alg":"HS256"}' doesn't have a valid JSON format.

I've created a repo to reproduce this issue: https://github.com/hhandoko/graal-json-decoding-issue

Here's the relevant Graal native image compilation flags: https://github.com/hhandoko/graal-json-decoding-issue/blob/master/scripts/graal/bin/dist.sh#L73
